Superhuman Vision Coming to Mere Mortals

This is very promising. Even a monochrome solution imbedded in a contact lens or even on a pair of glasses has serious value. As well we are ultimately headed for larger lens structures able to cover the eyes while sharply expanding the available spectrum that can be perceived and switched on at will by the eye locating a trigger point.ET's infamous eye pieces are rapidly approaching operational reality. Better ,the weight is quickly disappearing as well.Better, this will allow built in capacity for detailed inspection of the natural world and anything else. I would like to observe the progress of damage in a tree branch caused by a virus. That capacity alone can hugely augment good husbandry.\

Imagine having an ultra high-resolution display built directly into a
pair of contact lenses. This could be the future of digital displays
thanks to scientists at Oxford University, who have adapted a material
currently used to store data on DVDs and transformed it into a radical
new display technology.

Writing in Nature today, they say the material could usher in a
new generation of displays that are thinner, lighter, with higher
resolution and lower power consumption than any existing technology.

They could even be mounted on flexible or transparent surfaces,
raising the possibility of applications beyond just e-readers and
smartphones to things such as car windshields and contact lenses.

The development relies on the same process that turns water
into ice cubes in your freezer. Many substances undergo changes in
structure when they change temperature, such as going from solid to
liquid, or crystalline to non-crystalline. These phase-change materials
are currently used for a wide range of applications, from computer
memory and rewritable DVDs to advanced forms of home insulation.

The team, led by Professor Harish Bhaskaran, was exploring
other uses of phase-change materials like germanium antimony tellurium
(GST), when they realized they might be able to use them to produce a
colour display.

They took a single layer of GST just nanometers thick and
sandwiched it between two ultra-thin layers of a transparent conductor,
and stuck that on top of a mirrored surface.

The researchers predicted that by varying the thickness of one
of the transparent layers, they could change the color of light that was
reflected back, and by changing the phase of the GST they could switch
it from one color to another. They then built a prototype to see if the
material could change from grey to blue when it was heated.

"We couldn't believe it. It worked on the first attempt. So we
tried it with a few other colors and it worked well," says Bhaskaran.
"I've been an experimentalist for a long time, and I've never seen
things work this well at the first attempt."

The researchers then used the head of an atomic force microscope to draw a monochromatic image on the surface.

They also constructed a single pixel using a transparent electrode,
which is a crucial step in producing a workable display technology.

Bhaskaran says the technology has many potential advantages
over existing displays. The layers of film are only nanometers thick,
the display can be ultra thin and light, and once an image is drawn on
screen it requires no power to keep it there.

And, because the pixels are only nanometers across, the
resolution of the screen is potentially far higher than what is
achievable with today's technologies, such as LCD and organic LED.

While it's still early days for the phase-change technology,
Bhaskaran and his team are hopeful that it might migrate from the lab
into electronics stores within several years.

"We have a patent filed and we are developing a monochrome
prototype," he says. "We want to show that it can render video on a
really small display to showcase the super high resolution that is
possible. Hopefully that'll be done by the end of 2015. If that works,
then we'll take it from there."

The technology is a highly novel use of an existing
phase-change material, says Dr John Daniels, senior lecturer in
materials science at the University of New South Wales. "It's an old
material technology being used for a new popular application," says
Daniels, who wasn't involved in the research.

However, there are still significant hurdles to overcome in turning it into a workable display technology.

"My big concern is the range of colors and contrast the
technology can produce. That's the big question mark: whether they can
make these materials competitive with the real market leader, which is
organic LED, in terms of quality."

But he concedes that this is a fast-moving industry, and new technologies can potentially gain dominance rapidly.

"It always is a long way from the first demonstration to the
first application. But this is a field where things can go from the lab
to application in a very short period of time because the dollars are so
big if they have something that's better than what's on the market at
the moment."

About Me

Jan 2015 - 3 Mil Pg Views, March 2013 - Posted my paper introducing CLOUD COSMOLOGY & NEUTRAL NEUTRINO rigorously described, September 2010 I am pleased to report that my essay titled A NEW METRIC WITH APPLICATIONS TO PHYSICS AND SOLVING CERTAIN HIGHER ORDERED DIFFERENTIAL EQUATIONS' has been published in Physics Essays(AIP) and appeared in their June 2010 quarterly. 40 years ago I took an honors degree in applied mathematics from the University of Waterloo. My interest was Relativity and my last year there saw me complete a 900 level course under Hanno Rund on his work in relativity,as well as differential geometry(pure math) and of course analysis. I continued researching new ideas and knowledge since that time and I have prepared a book for publication titled 'Paradigms Shift'. I maintain my blog as a day book and research tool to retain data and record impressions and interpretations on material read. Do join my blog and receive Four items of interest daily Monday through Saturday.
